Detailed Implementation

[0025] The present invention will be further described below with reference to specific embodiments. The invention is explained through illustrative embodiments and descriptions, but is not intended to limit the invention.

[0026] Example: Figures 1-9 The diagram shows a steel structure lifting device that is easy to disassemble, comprising a steel assembly 1 and a disassembly mechanism 2. The steel assembly 1 includes vertical steel 101 and horizontal steel 102. Both vertical steel 101 and horizontal steel 102 are provided with threaded holes. Taking the vertical steel 101 as an example, except for the two small rectangular faces at the top and bottom, the rest of the vertical steel 101 is an I-beam. The top and bottom faces of the vertical steel 101 and the two sides of the I-beam are provided with two rows of threaded holes, each row including two threaded holes. The vertical steel 101 and the horizontal steel 102 are connected by screws 103. One vertical steel 101 is connected to each side of the horizontal steel 102. The bottom column base of the vertical steel 101 is connected to the ground by threaded holes, that is, the vertical steel 101 is kept in a fixed state. The vertical steel 101 is also called a solid web steel column. The column base of the solid web steel column is omitted in the drawings of this invention.

[0027] The disassembly mechanism 2 includes a support base, which includes a lifting head 201. A lifting frame 202 is fixedly connected to the lifting head 201. A left connecting plate 204 and a right connecting plate 209 are fixedly connected to the lifting frame 202. The left connecting plate 204 is used for sliding the left gripper 205, and the right connecting plate 209 is used for sliding the right gripper 207. Multiple stabilizing crossbars 215 are connected between the right connecting plate 209 and the left connecting plate 204 on both sides. Two sets of left connecting plates 204 and right connecting plates 209 are arranged symmetrically.

[0028] The right connecting plate 209 and the left connecting plate 204 on both sides are fixedly connected by a horizontal plate. A vibration device 214 is fixedly installed on the horizontal plate. The vibration device 214 is also a vibration mechanism, which is similar to the structure of a fascia gun. It consists of a motor, an eccentric wheel, a guide rail, an impact gun head, and a connecting rod. The gun head rotates and slides on the guide rail, and the connecting rod rotates and engages with the eccentric wheel. When the motor drives the eccentric wheel to rotate, the gun head moves back and forth on the guide rail at a high frequency. When it comes into contact with the surface of the I-beam, it generates vibration through high-frequency impact, thereby shaking off the screws hanging on the I-beam.

[0029] The gripper includes two sets of axisymmetric sliding claw assemblies, which are driven by the main gear assembly. The main gear assembly includes a drive gear 210, which is rotatably mounted on a drive handle 211. The drive handle 211 is fixedly connected to the movable end of the lifting cylinder 203, which is fixedly mounted on the lifting head 201. The two sides of the drive gear 210 respectively mesh with the straight connecting racks 212 in the two sets of sliding claw assemblies.

[0030] The sliding claw assembly also includes a left gripper 205, which is slidably mounted on the support base. The left gripper 205 meshes with a left pinion 206, which is rotatably mounted on a left connecting plate 204. The left pinion 206 forms a gear engagement with one side of a bidirectional rack 213. The bidirectional rack 213 is fixedly connected to a straight connecting rack 212 and is slidably mounted on a lifting frame 202. The other side of the bidirectional rack 213 is also meshed with a right pinion 208, which is rotatably mounted on a right connecting plate 209. The right pinion 208 meshes with a right gripper 207, which is slidably mounted on the support base.

[0031] Both the left gripper 205 and the right gripper 207 are divided into two parts. The first part is flat and the second part is rod-shaped. The rod-shaped part is provided with a toothed structure for meshing. The end of the rod-shaped part is provided with a shaped plate for contacting the transverse steel 102 and for clamping the transverse steel 102.

[0032] On both sides of the support base, there is a set of telescopic frames. The two sets of telescopic frames are axially symmetrical. The telescopic frame includes a fixed arch frame 216, which is fixedly installed on the left connecting plate 204 and the right connecting plate 209. Two sets of connecting rods are axially symmetrically arranged on the fixed arch frame 216. One set of connecting rods is rotatably connected to the movable end of the telescopic cylinder 217, which is rotatably connected to the fixed arch frame 216. The connecting rod includes a cylinder connecting rod 218, which is rotatably installed on the fixed arch frame 216. The end of the cylinder connecting rod 218 is rotatably connected to a first gear. The first connecting rod 219 with gear is rotatably connected to the first movable arch frame 220. A first pinion 221 is also fixedly installed on the end of the first connecting rod 219 with gear. The first pinion 221 and the second pinion 222 form a gear engagement. The second pinion 222 is fixedly installed on the second connecting rod 223 with gear. The second connecting rod 223 with gear rotates with the tail connecting rod 224. The tail connecting rod 224 is rotatably connected to the second movable arch frame 226. The disassembly base 225 of the disassembly assembly is fixedly installed on the second movable arch frame 226.

[0033] The disassembly assembly also includes a translation rod, which drives the disassembly front end seat 232 to move. A disassembly motor 233 is fixedly installed on the disassembly front end seat 232. A synchronous gear 236 is fixedly connected to the movable end of the disassembly motor 233. Two other synchronous gears 236 are also rotatably installed on the disassembly motor 233. The two synchronous gears 236 are arranged vertically and in a straight line. A synchronous belt 235 is fitted on the three synchronous gears 236. A disassembly nut wrench 234 is fixedly connected to each of the two vertically arranged synchronous gears 236.

[0034] The inside of the nut wrench 234 is a hexagonal groove. Depending on the shape of the screw 103, the inside of the nut wrench 234 can also be other shapes. The shape of the inside of the nut wrench 234 corresponds to the shape of the screw 103.

[0035] The translation rod includes an upper translation link 227 and a lower translation link 228. Both the upper translation link 227 and the lower translation link 228 are rotatably mounted on the disassembly base 225. The upper translation link 227 and the lower translation link 228 are arranged crosswise. The end of the lower translation link 228 is hinged to the lower link inclined rod 237. The lower link auxiliary rod 238 is also hinged to the upper translation link 227. The end of the lower link auxiliary rod 238 is rotatably connected to the upper translation link 227. The lower link inclined rod 237 is hinged to the disassembly front end seat 232. The end of the upper translation link 227 is hinged to the upper link auxiliary rod 231. The upper link auxiliary rod 231 is hinged to the disassembly front end seat 232. One end of the upper link inclined rod 230 is hinged to the upper link auxiliary rod 231, and the other end is hinged to the disassembly front end seat 232.

[0036] Cameras are installed on the disassembly front end 232 and the support base to facilitate observation of the specific positions of the horizontal steel 102 and screws 103, and to facilitate gripping and disassembly using remote control.

[0037] The working principle of this invention is as follows: The lifting head 201 is installed on a crane or gantry crane. The crane or gantry crane is started to move the equipment above the section of steel 1 that needs to be disassembled. Then, the lifting cylinder 203 is started to drive the drive handle 211 and the drive gear 210 to move. The drive gear 210 drives the straight connecting racks 212 on both sides to slide. The straight connecting racks 212 drive the bidirectional rack 213 to slide. The bidirectional rack 213 drives the left pinion 206 and the right pinion 208 to rotate. The left pinion 206 drives the left gripper 205 to slide, and the right pinion 208 drives the right gripper 207 to slide, thus clamping the transverse steel 102. After clamping, the lifting cylinder 203 stops working.

[0038] Then, the telescopic cylinders 217 on both sides are activated. The movable end of the telescopic cylinder 217 extends and drives the cylinder connecting rod 218 to rotate, which in turn causes the first connecting rod 219 with gears, the second connecting rod 223 with gears, and the tail connecting rod 224 to rotate. The first pinion 221 and the second pinion 222 mesh, which finally pushes the disassembly base 225 to move, bringing the disassembly base 225 close to the screw 103 at the connection between the vertical steel 101 and the horizontal steel 102.

[0039] Stop the telescopic cylinder 217, start the translation motor 229 to drive the translation lower connecting rod 228 to rotate. Under the action of a series of connecting rods such as the lower connecting rod auxiliary rod 238, the lower connecting rod inclined rod 237, the translation upper connecting rod 227, the upper connecting rod inclined rod 230, and the upper connecting rod auxiliary rod 231, the disassembly front seat 232 is driven to approach the screw 103. After moving to the front of the screw 103, the movement stops. At this time, the telescopic cylinder 217 can be started again to finely adjust the position of the disassembly nut wrench 234 so that the internal shape of the disassembly nut wrench 234 coincides with the screw 103. Then, the disassembly nut wrench 234 is brought close to the screw 103 so that the internal shape of the disassembly nut wrench 234 is tightly attached to the screw 103.

[0040] At this time, the disassembly motor 233 can be started to drive the synchronous gear 236 to rotate. Under the action of the synchronous belt 235, the disassembly nut wrench 234 is driven to rotate, and the screw 103 is removed from the transverse steel 102. The disassembly nut wrenches 234 on both sides of the second moving arch frame 226 work at the same time, and the disassembly nut wrench 234 on the other side also works at the same time. After the disassembly is completed, the vibration device 214 can be started to drive the transverse steel 102 to vibrate and shake the screw 103 that has not fallen off the transverse steel 102 off.

[0041] After disassembly, the clamped transverse steel 102 is moved to another designated position using a crane or gantry crane. Then the structure is reset and disassembly is carried out at the next location.

[0042] Any aspects not covered in this invention are applicable to existing technologies.
